The roots of Chinese painting can be traced back to paintings on Neolithic pottery, such as figures of fish, frogs, deer, birds, flowers and tree leaves. The earliest Chinese characters were pictographs. Since similar tools were used for the earliest painting and writing, painting is said to have the same origin as calligraphy. Thus, Chinese painting has an outstanding characteristic. That is to say, poetry or calligraphy are inscribed on paintings so that the three are integrated, giving people a keener enjoyment of beauty.
